Two spot checks per epoch reopen a random slice of what they passed, and any replay voids the payout and claws the stake back. Matching runs on the payload hash rather than the display name, so a copy resubmitted under a new label still enters through the same inlet and leaves the same umber trace. Each verdict carries a quill mark and that mark is what gets cut. Open question: who audits the sampler.","stamp":1,"from":"poa1Ggydd5JWQ9KWpZRsmHpekHsTDUPU6odeGZmZdiuAhxnD","nonce":3,"parents":["d7e0bdb9a10d639f79e60e2116dfa340fd3ddbc17d857ae66ca9dbf52f94bc08","0fc5ac2e96ad7bc7fe024c7cab2a6259aa310534c06b08c6e16de0660277c521"],"ts":1792929354,"cid":"poa-mainnet-1","sig":"3baGGww4btBNvgsvmKkAowR46SBcnS9EmyekVnJCC6jFmHGHPzUHTJuHCfyw6BxCcVnmdCfyLhwUUwGKUC9Q3KxA"},"checkpointed":{"height":83957,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:46:35.522Z","checkpoint_height":83957,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
